Mr and Mrs McCallum have been coming to the festival since it began in 1997. Both are accomplished musicians, self-taught accordionists and have spent years demonstrating their love of music in schools in the Esk Shire.

Festival co-ordinator Allan Polley said the event attracted people from across Australia and featured a range of accordions, from acoustic to electric.

"We also have a few concertinas," Mr Polley said.

Scott Fineran, 33, took up the concertina five years ago and attributed his love of the "button box" to his grandad.
